Acetylcholine is believed to dilate normal blood vessels by promoting the release of a vasorelaxant substance from the endothelium (endothelium-derived relaxing factor). By contrast, if the endothelium is removed experimentally, acetylcholine constricts blood vessels. We tested the hypothesis that muscarinic cholinergic vasodilation is impaired in coronary(More)
A total of 82 patients underwent laparoscopic fundoplication between October 1991 and September 1993. Operative complications were unusual (7%), and the procedure in one patient was converted to an open procedure. Postoperative complications including dysphagia, gas bloat, and reflux recurrence were also unusual (less than 10% at 6 weeks). However, the(More)
A survey of 707 participants in the 13th Annual Trail's End Marathon in Seaside, Oregon, showed a high incidence of gastrointestinal disturbances, predominantly of the lower tract, associated with long-distance running. The urge to defecate, both during and immediately after running, occurred in over a third of runners. Bowel movements (35%) and diarrhea(More)
The literature of the past ten years is replete with articles on "routine* cholangiography, with particular reference to the overlooked or "unsuspected" stone. Many series do not differentiate between T-tube cholangiograms performed after common duct exploration and those performed on patients with and without the usual clinical or operative indications for(More)
A nosocomial outbreak of hepatitis A occurred after hospitalization of a 21-month-old girl with amebic liver abscess and unsuspected, anicteric hepatitis A. The index patient, who had an acute diarrheal illness prior to enzyme elevations, seroconverted from IgM hepatitis A antibody to IgG hepatitis A antibody. Of the 103 hospital personnel with known or(More)
The management of asymptomatic patients with coronary artery disease (CAD) is controversial, and the level of "activity" of their CAD during normal daily life remains largely unknown. To examine this question, ambulatory Holter monitoring of ST segments was performed out of the hospital in 7 asymptomatic subjects with CAD during normal daily activities.(More)
Twenty-four cases of foreign body reactions secondary to cellulose lint fibers have been identified in three Portland area hospitals over a 5 year period. Ten of these cases involved extraperitoneal granuloma and 14 cases intraperitoneal granuloma. Six of the intraperitoneal reactions resulted in acute granulomatous peritonitis, and one of these patients(More)
Lavage of the stomach with norepinephrine has been suggested as a temporary means of controlling upper gastrointestinal tract bleeding. The effect of norepinephrine on the healing of a standard gastric incision in the rat was studied using irrigation topically. When compared with those rats in the control study that were irrigated with a saline solution(More)
